I want to create a buffer in meters around points in Europe. But I cannot find a proper CRS for Europe that is in meters instead of degrees?
I suggest to use one of the LAEA or LCC Europe projections:
EPSG 5633, 5635, 5636, 5638 LAEA Europe
EPSG 5632, 5634, 5637, 5639 LCC Europe
All EPSG codes of the same type seem to have the same projection parameters.
ESRI also offers projections Europe_Albers_Equal_Area_Conic (102013) and Europe_Equidistant_Conic (102031), but they almost look the same.
It sounds like you are trying to use Geographic Coordinate Systems which are for locating points on a sphere (over-simplification). In order to do buffers and measurements, you need to use a Projected Coordinate System, which flattens the sphere out to plane. All projections will introduce some distortion in shape, area, distance, and/or direction. You simply have to select one that looks the best for your purpose. Andre has suggested several. You can also create your own custom projection. ESRI has put out a nice pdf you can find here that explains map projections and might help you to better understand and select/create an appropriate one for your purposes.
