EU-Commission Directive on Corporate Sustainability Due Diligence

 

On 23 February 2022 the EU Commission adopted a proposal for a directive on corporate sustainability due diligence. The directive is instrumental in driving companies to mitigate adverse impacts on human rights, such as child labor and exploitation of workers, and environmental degradation, including pollution and biodiversity loss. The initiative underscores the pivotal role of corporations in fostering a sustainable economy and society, compelling them to scrutinize and address the negative implications of their operations, subsidiaries, and value chains.

Key benefits delineated for various stakeholders include improved protection of human rights and the environment, heightened consumer trust and transparency, and enhanced access to justice for victims. For companies, the proposal promises a harmonized legal framework across the European Union (EU), facilitating legal certainty and a level playing field, while also improving risk management and access to finance. The mentioned rules aim to benefit developing countries by bolstering human rights protections, raising sustainability awareness, and fostering sustainable investments.

The obligations set forth for companies and their directors are extensive. Companies are required to conduct due diligence to identify, prevent, mitigate, and account for negative human rights and environmental impacts within their operations. Moreover, large companies must devise a plan to align their business strategies with the goal of limiting global warming to 1.5 °C, consistent with the Paris Agreement. Directors are mandated to implement and oversee these due diligence processes and incorporate them into corporate strategies, taking into consideration the long-term human rights, climate change, and environmental consequences of their decisions.

The directive will apply to two main groups: Group 1 encompasses large EU limited liability companies with over 500 employees and a turnover exceeding €150 million, and Group 2 includes companies with more than 250 employees and over €40 million in turnover operating in high-impact sectors such as textiles, agriculture, and mineral extraction. The implementation will stagger, with Group 2 companies being subject to the rules two years after Group 1. Small and Medium Enterprises (SMEs) are not directly targeted by the proposed rules but will receive support to manage indirect effects.

Enforcement mechanisms include administrative supervision by designated member state authorities and a European Network of Supervisory Authorities to ensure a coordinated approach. Moreover, civil liability provisions will ensure compensation for victims arising from non-compliance with the directive’s obligations.

Steel, the backbone of modern infrastructure, has long carried a heavy environmental cost. Each year, nearly two billion metric tons of steel are produced globally, with the traditional process emitting around two tons of carbon dioxide per ton of steel. This makes the industry responsible for approximately 8% of global carbon emissions, exceeding the output of aviation. Against this backdrop, the Swedish startup Stegra, formerly H2 Green Steel, has emerged as a pioneer, aiming to transform steel production using green hydrogen. With nearly $7 billion raised and a plant in northern Sweden set to begin operations in 2026, Stegra is leading the charge toward a zero-emission future. Stegra’s innovative approach relies on green hydrogen produced through renewable energy sources like hydropower and wind. The hydrogen removes oxygen from iron ore, leaving metallic iron, which is further processed into steel in an electric arc furnace. This method eliminates the carbon emissions inherent in conventional steelmaking, replacing them with water vapour. Stegra’s Boden plant, the first of its kind at an industrial scale, will produce 2.5 million metric tons of green steel annually at launch, scaling up to 4.5 million metric tons. Although unproven on this scale, the process holds immense promise...
Sustainable technology aims to reduce humanity’s ecological footprint by improving processes and products in ways that preserve environmental integrity. Such technology can lower carbon emissions through either its manufacture or its operation, and often both. Developers integrate sustainable innovations across industries, from consumer electronics to large-scale infrastructure, acknowledging a shared imperative to mitigate environmental impact. Firms like Fairphone illustrate the principle, using ethically sourced and recycled materials in smartphones and providing long-term software support. This approach increases devices’ longevity and avoids needless electronic waste. Agricultural practices demonstrate that sustainable technology is not confined to small consumer items. Drones survey crop health, apply fertiliser and optimise water use through machine learning-based solutions, minimising the need for heavy machinery that compacts soil and burns fossil fuels. In architecture and residential construction, emerging systems harvest rainwater for domestic applications like toilet flushing. Electrochromic glass complements this by darkening in response to conditions outside, enabling more efficient climate control. Well-established solutions, such as solar panels, also exemplify sustainable innovation. Recycled materials for insulation further bolster the shift towards greener building practices, while in healthcare, electronic health records reduce paper use and facilitate cross-institutional data sharing. Virtual try-on systems in fashion reduce waste from returns,...

Global greenhouse gas emissions are projected to reach a record high in 2024, with fossil fuel and industrial emissions hitting 37.4 billion metric tons of carbon dioxide—up 0.8% from last year, according to the Global Carbon Budget report. While China leads as the largest current polluter, emitting twice as much as any other country, the United States holds the top spot for historical emissions, contributing 24% of all climate pollution since the industrial revolution. The European Union, the US, and China dominate discussions on climate responsibility, yet per capita emissions paint a different picture, with countries like Australia, Saudi Arabia, and Canada topping the list. This complexity underscores the need to view climate responsibility beyond today’s emissions, factoring in historical contributions and disparities in population and economic capacity. International negotiations, such as COP29 in Azerbaijan, highlight the tension between nations over who should contribute most to climate finance and mitigation efforts. Solutions must balance historical accountability with present-day realities, ensuring fairness for developing nations while encouraging collective action. Experts emphasize that without global cooperation, the atmosphere remains a shared resource, and the impacts of inaction will continue to transcend borders.
At COP29 in Azerbaijan, wealthier nations pledged a record $300 billion annually by 2035 to help poorer countries combat climate change. While this represents an increase in funding, it fell far short of the $1.3 trillion requested by developing nations, leading to sharp criticism. India denounced the sum as “paltry,” while small island states, facing existential threats from rising seas, called the deal inadequate. The summit, which stretched 33 hours past its deadline, revealed deep divisions between the global north and south, with bitterness overshadowing the applause for the agreement. This funding aims to assist vulnerable nations in transitioning to renewable energy and preparing for the impacts of climate change. However, it includes a mix of grants and loans, further straining trust. Critics like Greenpeace labelled the deal “woefully inadequate,” and some NGOs described it as a “death sentence” for millions. The controversy is compounded by geopolitical tensions, with concerns that future US climate leadership under Donald Trump could derail progress, prompting negotiators to ensure long-term commitments. Host country Azerbaijan faced scrutiny, as its oil-dependent economy and authoritarian leadership clashed with the summit’s goals. The challenges of shepherding 200 nations to agreement exposed weaknesses in the COP process, with calls...

The WMO State of the Climate 2024 Update once again issues a Red Alert at the sheer pace of climate change in a single generation, turbo-charged by ever-increasing greenhouse gas levels in the atmosphere. 2015-2024 will be the warmest ten years on record; the loss of ice from glaciers, sea-level rise and ocean heating are accelerating; and extreme weather is wreaking havoc on communities and economies across the world. The January – September 2024 global mean surface air temperature was 1.54 °C (with a margin of uncertainty of ±0.13°C) above the pre-industrial average, boosted by a warming El Niño event, according to an analysis of six international datasets used by WMO.
The Federal Council of Switzerland has endorsed a report advocating for carbon-neutral aviation by 2050, highlighting sustainable aviation fuels (SAF) as a crucial strategy for diminishing fossil CO2 emissions. This initiative, responding to a postulate from the House of Representatives’ Environment Committee, also acknowledges the importance of efficiency improvements in aircraft fleets and operations. However, the potential of hydrogen-fuelled and electric aircraft to significantly reduce emissions is deemed limited until 2050. To support the aviation industry’s transition to carbon neutrality, the federal government plans to implement new subsidies, complementing existing and future mechanisms outlined in the CO2 Act post-2024 for a 70% reduction in carbon emissions from Swiss air traffic. Nonetheless, achieving the net-zero target by 2050 will also necessitate carbon sequestration and storage technologies.
Australian engineers have developed a method to enhance concrete strength by nearly 30% using biochar made from spent coffee grounds. This innovative approach, involving a low-energy pyrolysis process, not only strengthens concrete but also offers environmental benefits by reducing the need for natural sand in construction. The technique, still in early stages, could significantly decrease organic waste in landfills while preserving natural resources. This advancement in recycling coffee waste into construction materials marks a significant step towards sustainable construction practices.
Agrivoltaics, the integration of solar panels with agriculture, offers a dual benefit of clean energy production and agricultural use, but its impact on crop yields has been uncertain. A comprehensive review of 54 global agrivoltaic operations by researchers from Bern University of Applied Sciences and Agroscope reveals varied results. While some crops like potatoes and sweet peppers thrive under solar panels, others like garlic and basil see yield reductions. The study, published in Renewable and Sustainable Energy Reviews, highlights the complex interplay of factors influencing agrivoltaic efficiency, including light exposure, heat stress, and crop type adaptability. Promising results for maize in South Korea and Japan suggest potential for staple crops under optimized conditions, though more research is needed for berries and fruits. Innovative solutions like Insolight’s clear solar panels, which adjust sunlight for plant needs, show promise for enhancing agrivoltaic system productivity.
