Emissions reduction projects, technologies and carbon capture usage and storage (CCUS)

International emission reduction treaties

Emission reduction projects aim to reduce carbon dioxide (CO₂) and other greenhouse gas (GHG) emissions. They often generate carbon credits which can be traded in international or voluntary markets.

UNFCCC and Kyoto Protocol

The United Nations Framework Convention on Climate Change (UNFCCC), and the connected Kyoto Protocol, are key international treaties connected with stabilising GHG concentrations. For more information, see Practice Note: UNFCCC 1992—snapshot.

The Kyoto Protocol committed developed economies in Annex I to the UNFCCC (Annex I parties) to detailed reductions in GHG emissions through a number of methods, including flexible mechanisms, such as the Clean Development Mechanism (CDM), and Joint Implementation (JI). The CDM and JI involved investing in emissions reduction projects in developing countries (CDM) and developed countries (JI). The Kyoto Protocol ran for two commitment periods: 2008 to 2012, and 2013 to 2020.

Commission releases explanatory guide on REACH microplastics restriction

The European Commission has published an Explanatory Guide to support implementation of the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) microplastics restriction, which came into effect on 17 October 2023. The guide, developed with the European Chemicals Agency, includes implementation provisions, Q&A sections, and decision trees for borderline cases. Part I will be translated into 22 EU languages by Q3/2025. The restriction aims to prevent 500,000 tonnes of microplastic release over 20 years, with specific transitional periods ranging from 2027 to 2035 for various products including cosmetics and detergents.

Commission proposes flexible CO2 compliance period for automotive manufacturers

The European Commission has proposed on 1 April 2025 an amendment to the Regulation on CO2 emission performance standards for new cars and vans. The amendment introduces flexibility in how manufacturers can meet their CO2 targets between 2025-2027, allowing compliance to be assessed as an average across the three-year period rather than annually. The change aims to help manufacturers balance emissions while maintaining investment capacity for clean transition, without altering the original 2025 emissions reduction targets. The European Commission has requested co-legislators to expedite agreement on the amendment to provide certainty for industry stakeholders.

Dan Corry’s independent review examines Defra’s regulatory framework

The Department for Environment, Food and Rural Affairs (Defra) has published the findings of Dan Corry’s independent review, which examines whether Defra’s regulatory framework effectively supports economic growth and nature recovery. The review identifies the current system as outdated, inconsistent, and complex, presenting 29 recommendations across five strategic themes. In response, Defra announced plans to expedite the implementation of nine key recommendations, including: (1) appointing a single lead regulator for major infrastructure projects; (2) rapidly reviewing and updating existing environmental compliance guidance; (3) streamlining permit processes, including updating the Environmental Permitting (England and Wales) Regulations 2016, SI 2016/1154; (4) developing a single planning permit portal for all agencies; (5) establishing a new Defra Infrastructure Board; (6) granting increased autonomy to trusted nature conservation and environmental partners; (7) launching an industry-funded Nature Market Accelerator; (8) publishing new strategic policy statements for all regulators, starting with the Environment Agency and Natural England; and (9) introducing a continuous reform programme for specific regulations. Measures involving financial expenditure will be evaluated during the Spending Review, while those requiring legislative changes will be considered within Defra’s broader legislative priorities.

FCA updates webpage on sustainable finance discussion paper DP23/1

The Financial Conduct Authority (FCA) has updated its webpage to reflect feedback received on the discussion paper ‘DP23/1: Finance for Positive Sustainable Change’ that was published in February 2023. The FCA says the responses received were generally positive about the importance of sustainability matters and the themes outlined in DP23/1. However since publishing DP23/1, the FCA notes that it has introduced rules related to some of the themes, including the Consumer Duty, Sustainable Disclosure Requirements (SDR) and labelling rules, and the Anti-Greenwashing Rule and is therefore not currently considering introducing new rules on the themes discussed in DP23/1. Instead the FCA says it will continue to promote the themes discussed in DP23/1 through other initiatives, both domestically and internationally.
