Offshore Wind Science and Research RFP

Massachusetts remains committed to offshore wind as a key energy source to provide critically needed energy, spur economic development, and create good-paying jobs. MassCEC recognizes that offshore wind development occurs in a dynamic ocean environment that supports existing marine industries of economic and cultural importance, is inhabited by critically endangered wildlife, and is itself undergoing climate-induced changes. These variables, among others, present a wide range of technical, logistical, and analytical research opportunities related to the offshore wind industry, particularly now that several projects have or soon will reach commercial operation. Focused science and research activities, and the organizational capacity to conduct that science and research, are needed in the near- and long-term to inform, optimize, and catalyze industry growth.   

The 2026 RFP will fund up to $2.5 million for projects aligned with priority research areas identified by MassCEC. While a broad array of research projects will be eligible to apply, this round of funding has also specified topic areas of interest within each of the following categories:

• Fisheries: Understanding Effects in Southern New England Lease Areas
• Wildlife and Habitat
• Regional Transmission Planning
• Gulf of Maine Regional Monitoring
• Communicating Existing Science and Research

MassCEC has allocated up to $2.5 Million Dollars ($2,500,000) in funding for awards and commitments under the Solicitation. We expect that awards will range from approximately $50,000 to $500,000. An application proposing higher amounts of MassCEC funding must present a compelling case for the funding need and potential outcomes toward achieving the Objectives.

Young Health Programme

The Young Health Programme (YHP) is a global disease prevention initiative, aiming to provide education for young people to feel empowered to make informed choices about their health and catalyse a global, youth-led advocacy movement.

The programme operates in over 40 countries and partners with more than 60 non-profit organisations, including UNICEF and Plan International. The YHP combines community programmes, research, advocacy, and the development of young leaders, with a focus on underserved communities.

Since its launch in 2010, the YHP has directly reached over 23 million young people, trained over 1 million, and engaged more than 23,000 AstraZeneca employees, who have volunteered their time with more than 140,000 hours.

The YHP aims to prevent the most common non-communicable diseases (NCDs), including cancer, diabetes, heart disease and respiratory disease, by addressing five main risk factors: tobacco use, unhealthy diet, physical inactivity, harmful use of alcohol, and air pollution. Additionally, the programme tackles climate-health impacts to build healthier communities, recognising, as projected in the IPCC Sixth Assessment Report, that children born after 2010 will be the first generation to enter adulthood in a world where the average temperature will reach 1.5°C above pre-industrial levels, and are expected to experience a +2°C rise within their lifetime.1

AstraZeneca Young Health Programme Impact Fellowship 2026

AstraZeneca is looking for passionate, driven young leaders to join their 2026 Young Health Programme (YHP) Impact Fellowship. The Fellowship supports young advocates to create actionable change to: 

• Advance health equity – with a focus on acting early to prevent non-communicable diseases among young people, or supporting young people living with rare diseases.
• Take action on climate and nature – advocating for the mitigation of the harmful effects of climate change on the health and well-being of young people.
• Build health systems resilience – contributing to stronger health systems that prioritise earlier intervention to meet today’s needs and mitigate tomorrow’s disease burden.

Benefits

The selected Fellows will gain access to networks, funding and development opportunities, enabling them to drive a global health movement led by and for young people:

A fully-funded scholarship to attend the 2026 One Young World Summit in Cape Town, South Africa (3–6 November 2026) as well as access to the One Young World Ambassador Network and the Young Health Programme (YHP) Alumni group of other young changemakers working to improve youth health.

Structured learning and development offerings to enable them to scale their impact, including both self-directed and live learning. This includes access to the One Young World Academy, an award-winning mini-MBA programme, mentorship from AstraZeneca colleagues and professional training.

Each selected Fellow will receive a grant of either USD $10,000 or USD $50,000 (if selected as the Lead2030 winner** for Sustainable Development Goal 3, for which applicants will be automatically considered) from AstraZeneca, through their non-profit organisation. Fellows are expected to use the grant to implement a project focused on either (1) advancing health equity (2) taking action on climate and nature (3) building health systems resilience.

The Onion Foundation's Environment Program aims to enhance nature learning for Maine's youth, especially in underserved rural areas. By providing high-quality, science-based educational opportunities, the program seeks to cultivate an appreciation for natural systems and their importance to a vibrant life. Key priorities include developing standards-aligned nature programs and facilitating transformative outdoor experiences. This initiative addresses educational disparities, ensuring all children can benefit from rich environmental education and engagement with their local ecosystems.
