text: **Major environmental changes and policies**influence OSH.**The enhanced and accelerated**
  **introduction of environmental technologies is widely supported by national and EU policies.**
  *(Green deal283 and circular economy.*284*)*Consequently, the number of workers in these sectors will 
  increase and impact the working conditions of many workers. Sectors/enterprises dealing with 
  sustainable technologies grow fast, for example, decentralised and carbon-free energy production, 
  green products, waste and recycling, green mobility and transport, and energy saving buildings’ 
  renovation. These ‘green jobs’ have gained a relevant and sometimes essential share in several 
  economic areas.285 
  
  Sectors like**construction and crafts**will profit significantly from this development. That would also 
  mean that sector-typical OSH risks — accident risks — will ‘return’. Also new risks will emerge, a circular 
  economy approach 286 will pose additional**risks in recycling and waste treatment**, due to more 
  handling of contaminated materials and probable exposure to more chemical contaminants and 
  infectious biological agents. 
  
  EU-OSHA summarises:*‘The new technologies or working processes associated with green jobs can*
  *lead to new hazards, which call for new combinations of skills to deal with them: the “old” OSH*
  *knowledge cannot simply be transferred to them. Installing a solar water heater, for example, involves*
  *combining the skills of a roofer, a plumber and an electrician.’*287
