Progress and Gaps in the Adoption of Clean Cooking Fuels in Africa – Policy Options for Ghana and Kenya

Progress and Gaps in the Adoption of Clean Cooking Fuels in Africa – Policy Options for Ghana and Kenya

Access to clean cooking fuels is vital for public health, environmental sustainability, and socio-economic development in sub-Saharan Africa. This study examines the key barriers to adopting clean cooking fuels in Ghana and Kenya, asking. Despite progress in urban areas toward liquefied petroleum gas (LPG) and electricity, rural households remain reliant on biomass fuels like wood and charcoal, leading to indoor air pollution and environmental harm. This dependence imposes significant costs, estimated at $18 billion annually in Ghana and $39 billion in Kenya. To address these challenges, targeted policy interventions—such as expanding LPG infrastructure, providing financial subsidies, and implementing culturally sensitive awareness campaigns—are essential. This study enhances understanding of Africa’s energy transition by highlighting the socio-economic and cultural dimensions of clean cooking adoption, supporting efforts for equitable access to sustainable energy solutions.

Carbon Dioxide Utilization in the Desalination Sector in Saudi Arabia: An Opportunity for Achieving Negative Emissions

Carbon Dioxide Utilization in the Desalination Sector in Saudi Arabia: An Opportunity for Achieving Negative Emissions

The global pursuit of sustainable solutions to mitigate climate change has intensified, necessitating innovative approaches that transform traditional carbon-intensive industries into potential carbon sinks. Carbon capture, utilization and storage (CCUS) is a key tool for achieving net-zero targets by 2060 in Saudi Arabia. The country has set targets to achieve 9 megatons per year (Mt/y) of CCUS by 2027 and 44 Mt/y by 2035. Recent work has characterized the Kingdom’s geological carbon dioxide (CO2) potential as around 445 gigatons (Gt), but to date, there has been no detailed analysis of the CO2 utilization potential in the Kingdom. Current research at KAPSARC aims to review existing and emerging CO2 utilization routes relevant to Saudi Arabia. This paper focuses on evaluating the untapped potential for CO2 utilization in the Kingdom’s desalination sector and explores the potential of this sector to become a carbon sink, thus contributing to carbon dioxide removal (CDR). Results show that, by 2030, the desalination sector in Saudi Arabia could store up to 458 million tons of CO2 annually in the brine discharged from desalination plants, transforming brine into a useful product and reducing environmental impacts while also potentially creating negative emissions. The study recommends that policies are introduced to encourage a circular carbon economy (CCE) approach within industry. Policies and regulations supporting the installation of brine recovery equipment as well as CO2 capture and utilization (CCU) are considered a priority for the desalination sector. Encouraging CCU from atmospheric and biogenic origins is attractive as it provides the potential for carbon removals and offsetting in the desalination sector as Saudi Arabia transitions to a net-zero carbon economy.

Saudi Arabia Net-Zero GHG Emissions by 2060: Transformation of the Transport Sector

Decarbonizing the transport sector will likely play a crucial role for Saudi Arabia in fulfilling its target of reaching net-zero greenhouse gas (GHG) emissions by 2060. While clear and immediate low-carbon or zero-carbon alternatives exist in some sectors, the transport sector faces challenges. For instance, there are promising solutions for passenger cars, but solutions for long-distance transport are still being developed or are in the early adoption phase. Understanding these challenges requires a comprehensive study of Saudi Arabia’s transport sector and the long-term impact of various policies on the industry.

Closing the Investment Gap to Achieve Paris Agreement Goals

Closing the Investment Gap to Achieve Paris Agreement Goals

This study aims to assess the alignment of global sustainable financial flows with transition investment priorities. First, we identify investment gaps based on the difference between the required annual investment to meet global net-zero emissions (NZE) targets and current investment flows. Our assessment reveals that nearly all countries must significantly accelerate their efforts, as their current investment levels fall short of what is required. Second, and perhaps more importantly, investment gaps are particularly large for non-Annex I (developing) countries. Financing these large-scale investments continues to be a major global challenge. The size of global environmental, social and governance (ESG) finance remains low. Specifically, despite their large investment gaps, developing countries receive only a minor share of global ESG funds, where access to conventional finance is already limited.

Role Of LPG In Enabling A Just And Inclusive Energy Transition In Africa And The Arab Region

Role Of LPG In Enabling A Just And Inclusive Energy Transition In Africa And The Arab Region

Globally, 2.3 billion people still lack access to clean fuels and technologies for cooking (CFTs) today, with an overwhelming majority residing in rural areas. Without a dramatic increase in investment and action for scalable solutions, 1.9 billion people will remain without access to clean cooking in 2030. This stark reality highlights the urgency for action, underlined by the Clean Cooking Alliance’s (CCA) strategy, which emphasizes the need for annual investments of at least $10 billion to achieve universal clean cooking access by 2030, compared with the existing funding shortfall of less than 1.5% of that value $130 million each year).
